Otologic pathophysiology in patients with human immunodeficiency virus.
During the initial phase of clinical diagnosis and treatment of the manifestations of acquired immunodeficiency syndrome, involvement of the ear appeared minor. In the past several years, however, otologic disorders increasingly have been reported in individuals with human immunodeficiency virus (HIV), as well as in retrospective studies of such patients. The otologic data appear quite variable. Functionally, conductive hearing loss, unilateral and bilateral sudden or progressive sensorineural hearing losses, vertigo, and tinnitus have been reported. In addition, tissue responses in each division of the ear have been observed. Based on collective serologic and immunologic diagnostic assays, clinical histories, and temporal bone histopathology, otologic symptoms may not be the direct effect of HIV alone, but rather a combination of the effects of HIV infection coupled with that of opportunistic microorganisms and/or possible ototoxic effects of certain therapeutic agents. It is within this context that otologic findings in this population of subjects will be discussed.
